HumanoidBench: Simulated Humanoid Benchmark for Whole-Body Locomotion and Manipulation

Paper Website

We present HumanoidBench, a simulated humanoid robot benchmark consisting of $15$ whole-body manipulation and $12$ locomotion tasks. This repo contains the code for environments and training.

Directories

Structure of the repository:

• data: Weights of the low-level skill policies
• dreamerv3: Training code for dreamerv3
• humanoid_bench: Core benchmark code
  • assets: Simulation assets
  • envs: Environment files
  • mjx: MuJoCo MJX training code
• jaxrl_m: Training code for SAC
• ppo: Training code for PPO
• tdmpc2: Training code for TD-MPC2

Installation

Create a clean conda environment:

conda create -n humanoidbench python=3.11
conda activate humanoidbench

# Install HumanoidBench
pip install -e .

# jax GPU version
pip install "jax[cuda12]==0.4.28"
# Or, jax CPU version
pip install "jax[cpu]==0.4.28"

# Install jaxrl
pip install -r requirements_jaxrl.txt

# Install dreamer
pip install -r requirements_dreamer.txt

# Install td-mpc2
pip install -r requirements_tdmpc.txt

# Install stable-baselines3 (PPO)
pip install stable-baselines3==2.3.2

Test Environments with Random Actions

python -m humanoid_bench.test_env --env h1hand-walk-v0

Test Environments with Hierarchical Policy and Random Actions

# Define checkpoints to pre-trained low-level policy and obs normalization
export POLICY_PATH="data/reach_two_hands/torch_model.pt"
export MEAN_PATH="data/reach_two_hands/mean.npy"
export VAR_PATH="data/reach_two_hands/var.npy"

# Test the environment
python -m humanoid_bench.test_env --env h1hand-push-v0 --policy_path ${POLICY_PATH} --mean_path ${MEAN_PATH} --var_path ${VAR_PATH} --policy_type "reach_double_relative"

Test Low-Level Reaching Policy (trained with MJX, testing on classical MuJoCo)

# One-hand reaching
python -m humanoid_bench.mjx.mjx_test --with_full_model 

# Two-hand reaching
python -m humanoid_bench.mjx.mjx_test --with_full_model --task=reach_two_hands --folder=./data/reach_two_hands

Change Observations

As a default, the environment returns a privileged state of the environment (e.g., robot state + environment state). To get proprio, visual, and tactile sensing, set obs_wrapper=True and accordingly select the required sensors, e.g. sensors="proprio,image,tactile". When using tactile sensing, make sure to use h1touch in place of h1hand. Full test instruction:

python -m humanoid_bench.test_env --env h1touch-stand-v0 --obs_wrapper True --sensors "proprio,image,tactile"

Paper Training Curves

Please find here json files including all the training curves, so that comparing with our baselines will not necessarily require re-running them in the future.

The json files follow this key structure: task -> method -> seed_X -> (million_steps or return). As an example to access the return sequence for one seed of the SAC run for the walk task, you can query the json data as data['walk']['SAC']['seed_0']['return'].
